Duotang

Inserting an exact replica of your cock into your woman's ass while your own cock is inserted in her vagina, or vice versa.

Dude... I bought this penis casting kit and made a latex replica of my unit. Then the other night when I was f**king Carrie from behind, I lubed it up and slid it in her ass. Totally DuoTang'ed her.

Duotang

a paper binder that is painful to use because of those sharp paper holder tabs

I just cut my finger on this obsolete duotang, I should not have been such a cheap skate and bought a real binder

A scene in a porno that involves 2 girls.
